Quality is the key, Samsung mobile phone battery battery explosion

The explosion of mobile phone charging has been commonplace. Many of the main reasons for the spontaneous combustion of Lithium Batteries are the long charging time and the lack of using a regular brand of mobile phone chargers, resulting in lithium batteries becoming a latent "grab" under special uncertainties. It always threatens the personal safety of mobile phone users.

Recently, Reddit, a famous foreign social news site, was exposed. A Samsung GALAXY S3 user suddenly spontaneously ignited during the charging process of the mobile phone. The whole battery has been fully inflated, and the rear casing and the fuselage of the mobile phone also left obvious burning marks. It was also burned out of a hole, and the entire second floor was filled with unpleasant smell. Fortunately, the owner did not cause too much casualties and property damage, and the owner's fingers were slightly injured.

Looking at the number of such mobile phone explosions, the main reasons for the explosion of mobile phones are twofold:

1. Battery quality problems: The counterfeit Lithium Battery is an important cause of the explosion of lithium batteries. Many cottage lithium batteries are caused by excessive raw material impurities, unqualified manufacturing processes, and inadequate design of battery safety protection.

2. The battery has no safety protection: in the state of long-term charging, the current is too large, the voltage is too large, and the power supply is excessively heated, which causes the mobile phone to be unable to be used normally. Moreover, lithium batteries may instantaneously discharge under special conditions of temperature, humidity and poor contact, and generate a large amount of current, causing spontaneous combustion or explosion.

Generally, the regular lithium battery will strictly control the quantity and size of the chips in the battery. At the same time, the lithium battery produced by the regular manufacturer uses flame-retardant materials, so the quality of the lithium battery is in normal use. It is not easy to explode in the process. However, some manufacturers who cut corners will take advantage of the raw materials in order to gain profits, resulting in the production of batteries that do not meet the standard of standards, which has laid the foundation for mobile phone accidents.

In addition, the reason for the explosion of mobile phones is not only the quality of the products themselves, but also human factors. To this end, experts recommend:

1. Do not buy a poor quality mobile phone battery or mobile phone charger, you must buy the original production battery or a mobile phone charger produced by a regular brand manufacturer, do not make a bane for the sake of small profits.

2. Do not charge at low temperature or high temperature. When the temperature is below 0 degrees Celsius, the amount of charge will be significantly lower than the normal amount, which will lead to insufficient reaction between the positive and negative electrodes, causing excess lithium ions to form crystals, causing the diaphragm to be pierced, causing a short circuit inside the battery. explosion.

3. Don't charge for a long time, and don't put the phone in a place where it is not easy to dissipate heat when charging. Nowadays, big-screen mobile phones are easy to consume electricity. Many people are used to hiding in the quilt and charging while playing mobile phones. The danger.

4. It is best not to charge the mobile phone when thunder lightning, so as to prevent the mobile phone from being damaged by lightning or causing human electric shock.
